Configuring Fiddler to watch specific domains

Question

I'm using Fiddler to monitor some HTTP traffic. I want to configure it to watch traffic from a few specific domains.

I know that

• CustomRules.js can be modified to manipulate traffic passing through fiddler

• oSession.HostnameIs("required.host.name") can be used to check the host name

• I want to check the host name in the OnBeforeRequest(oSession: Session) function

What I don't know is the syntax, or property I need to set to ignore or hide sessions.

Any ideas?

Answer 1

Manipulate the OnBeforeRequest function using the following syntax:

if (!oSession.HostnameIs("domainIcareabout.com") &&
        !oSession.HostnameIs("anotherDomainIcareabout.com"))
{
    oSession["ui-hide"] = "Hiding other domains"; // String value not important
}

This page on fiddlertool.com contains some script samples. Search for "Hide requests to domains except those I care about".
